ference on some zodiacal l ight photography that
was planned on later flights.
The first test
was to pitch straight down toward the earth,
open the shutter on the Contarex camera ind
actuate the pitch-up with the shutter open. Then we'd
take another picture and actuall y open the
shutter again and activate the pitch-down thrusters,
to see if these two thrusters would cause some
type of light interf erence to the photography.
On the pitch-down part of the phase, we waited
till the moon had set, and as we were pointed
down toward the earth, we came upon an area fa±rly
~i ear of clouds.
But,unfortunately,there were
a few soattered lights from homes or cities down
bel ow us , which might have caused some
interference.
I don ' t think so.
They were
very, very scattered.
The pitch-down test
was satisfactory.
The next one was the one in
which we were actually level with the horizon.
Again, Jim opened the shutter, I actuated a
pitch- up, and closed the shutter. He
opened it again, I actuated a pitch-down thruster,

and he closed the shutter. It was a pretty
simple test .
We took four pictures.
